This invention relates to machines for use in themanufacture of shoesforshaping uppers over lasts, and is 'herein illustrated in itsapplication to a "pulling-over machine constructed especially 5 for usein pulling over the uppers of stitchdown shoes. It is to be understood,however, that in some of its novel aspects the invention-is not limited'to pulling-over machines nor to machines for operating on shoes of thatparticular kind.

Pulling-over machines of the well-known type exemplified by thedisclosure of United States Letters Patent No. 1,029,387, granted onJune 11; 1912,:upon an application of R. F. McFeely have been -modifiedheretofore with the object of adapting them betteror use to pull overthe uppers-of stitchdown shoes, as illustratedin LetterslPatent'No.1,916,275, granted on July 4, 1933 upon "an application of James 1M.Matheu. As disclosed in the last-mentioned Letters Patent, after :thepulling-over grippers have been operated to pull the upper heig htwiseof the last, the upper is fastenedby'tacks'driven infdirections inclinedrelatively to the bottom =face of the last in locations substantially atthejunction of the bottom face and the upper-shaping surface of thelast,so that the marginal portion of the upper may :be readily turnedbutward and a sole or insole applied over the outt'urned margin whilesome or all of thetack-s-arestill inthe last. The upperfasteningdevicesare movable inwardly toward theshoe into upper-fasteningpositions and carry means for clamping the upper before the fasteningsare driven, 'such 'devices also acting in their inward movements torelease the grippers from the upper through contact with releasingmembers on the grippers.

One object of the present invention is to'affordincreasedinsurance thatin a machine op-i erating as above described the upper will be clampedand held securely in the proper relation tothe'last'inthe intervalbetween its release bythe grippers and the 'driving of the fastenings.For purposes of the invention the construction here-' in shownislaccordingly such that the'grippers in their upper-pulling movements"heightwise of I the last receive also :movements in directions to drawthe :upper inwardlybver the edge of the last bottom. serves not only toposition the marginal portion of the upper close t0 that :por-' tion ofthe last-against which it is to be clamped by the clamping -means, butalso to carry the gripper releasing members farther'away from theupper-fastening devices, so that I better insurance is afiorded a&inst' 1. .ase;0f thesrippers from. the upper by the inward movements ofthese devices before the clamping members arrive in clamping. positions.fThe ,above described inward 1 movements ,dfth'e' grippers .,areefie'cte d by overdraw springs w'itli which machines of. the illustratedtype arercustomarily provided, and torch; 5

The driving of the tacks precisely {the de, sired locations at thejunction of the bottomiace and ,the upper-shaping surface of thelastrequires .flthat the last .beaccurately positioned height wiserelatively to" the upper fas'tening devices. Qln machines ,of the[illustrated type the heightyvise position .of the ,lastgis determinedby a workl rest positioned opposite thebottom-fae of the last .andcomprising membersarranged respectively. at the end and the sidesof the;:forepartpithe last bottom. ,Since the bottomsmf the ,ioreparts .of.1a'sts.are.,frequently cunved more 01" less laterally as' well .aslengthwise, theicon structio'n herein. shown is such -,that the membersof the Iwork rest ;are' arrangecl to engage the :bottom face .of. thelast .in' locations as closeias is practicable ,to the points wherefastenings are driven. As j-illustrated, the side ,members of the work,rest [are thus .arranged to engage theYlast' in locations opposite thepoints where the ,rearmost side tacks are driven vand iat le ssdistances from ,fthe edge of the last bottom vthan the width ofjtheQmarginaI [portion .of the upper extending beyondsaid edge, and,theQend member. is .ar ranged to engage the last in a location directlyopposite-theypoint where the. .end tack is driven" V and in similarlyclose relation to the Ledge ,ofthe 45 last bottom For greater accuracywithrespect' to the locations of the tacks 'injoperagting on lasts ofdifferent styles and of differentsizesgprovision is also afforded 'bythis invention fo'rj-various adjustments of the -work rest memberspes-50 pecially- -of the side members",'=the latter in the constructionshown being ad justable heightwi's'e of .the-ilast relativelyxtoxtheend' member and also adjustablerawidthwise of the" lastrelatively to each other. In the construction of the work rest; andespecially in the provision for different adjustments of its sidemembers, novel features are to be recognized which are not limited touse on stitchdown shoes where the work rest engages the bottom face ofthe last, but are applicable also to work rests engaging a sole orinsole on the last.

The above and other novel features of the invention, including variousnovel details of construction and combinations of parts, will now bemore particularly described by reference to the accompanying drawingsand pointed out in the claims. f v y In the drawings,

Fig. 5 is a view similar to Fig. 4 with the parts in the positions thatthey occupy after the upperpulling operation and prior to the movementof the upper-fastening means into position for the driving of thefastenings; and

Fig. 6 is a view 'inthe direction of the arrow A in Fig. 2, illustratingmore clearly the relation between the last and shoe and certain portionsof the structure at the time when the fastenings section on the lineIII-III of are driven.

' As is well known, a machine of the type in which the invention isherein shown as embodied includes in its organization a gripper 10 (Fig.2) for pulling the upper atthe end. of the toe and grippers 12 forpulling it at'the opposite sides the grippers that'may be necessary toadjust the upper properly on'the last. When the machine is'againstarted, side clamp arms 16 are swung inwardly toward the sides of theshoe to clamp the forepart of the upper against the last and support thelast'for the upper-fastening operation. In the continued operation ofthe machine upper-fastening devices are moved inwardly into positions todrive upper-holding fastenings, these devices carrying additional meansfor clamping the upper to assist inholding it until the fastenings aredriven. Release of the grippers from the upper is effected by engagementof the inwardly moving upper-fastening devices with members 18 at theouter sides of the grippers,

whereupon thegrippers are moved farther upwardly and are also swunginwardly to make way-for the upper-fastening devices. After thefastenings have been driven the parts of the machine are returned totheir starting positions and the shoe is released.

In general similarity to the construction shown in the above-mentionedLetters Patent No. 1,916,- 275, the upper-fastening devices inthemachine herein shown are so constructed and arranged as to drive asingle tack at the end of the toe and two tacks at each side of theforepart, the tacks being driven in locations substantially" at thejunction of the bottom face and the upper-shaping surface of the last,i. e., the surface that gives shape to portions of the upper that arevisible in the finished shoe above the shoe bottom. Lasts which are usedin the manufacture of stitchdown shoes usually have a somewhat roundedor beveled contour, at the junction of the bottom face and theupper-shaping surface, and as disclosed in the above-mentioned LettersPatent the tacks are driven in this portion of the last at suchinclinations to'the bottom face of the last that the margin of the uppermay be readily turned outward and a sole or insole placed on the bottomof the last in engagement with the outturned margin while some, atleast, of the tacks are still in the last. The upper-fastening devicesatthe sides of the forepart are supported on arms 20. (Fig. 1) which areswung inwardly toward each other to carry the devices intoupper-fastening positions and which carry spring-operated driver bars 22connected by means of substantially the same character as disclosed inthe above-mentioned Letters Patent with tack drivers 24 inclined in thedesired angular relation to the bottom face of the last for the purposesin view. The upper-fastening device at the end of the toe is supportedon an arm 26 (Fig. 2) mounted to swing lengthwise of theshoe, this armcarrying a driver bar 28 connected to a tack driver 30 inclinedrelatively to the bottom facev of the last at substantially the sameangle as the side tack drivers 24. Each of the several upper-fasteningdevices includes apairof tack fingers 32 that provide atack pocket fromWhich the tack is driven by the driver.

In order that the tacks may be driven in proper relation to the bottomface and the upper-shaping surface of the last the inward movements ofthe upper-fastening devices must be stopped with these devices in properrelation to the last. -Accordingly the front arm 26 carries a stop 34arranged to engage the end of the shoe and thus limit the rearwardswinging movement of the arm while also clamping the upper against theend face of the last to assist in holding the upper until the tack isdriven. This stop is adjustable lengthwise of the shoe relatively to thearmv 26 and is held in adjusted position by a' clamping screw 36. Whilediffering in construction somewhat from the corresponding stop shown inthe previously mentioned Letters Patent No. 1,916,275, it performs thesame function as the stop therein shown. The means for limiting theinward movements of the upper-fastening devices that operate at thesides of the shoe is somewhat different from the disclosure of theabove-mentioned-Letters Patent. As herein illustrated, each side clamparm 16 carries a pair of clamp members 38 and 40 connected together byequalizing mechanism not shown in detail, but of substantially the sameconstruction as used frequently heretofore in machines of theillustrated type and similar to the disclosure of Letters Patent No.1,135,954, granted on April 13, 1915 upon an application of R. F. Mc-Feely. Each clamp member 40 clamps the upper upstate a ainst the sideQf. the last .below the locations wherethe side tacksare drivenandismounted, on a blo ck,142 sw,iveled for movement about ,an axis extendingheightwise of the last for automatic ad ustment to the lengthwisecontour of the side of the last vas determined by engagementof theclampmember 40 with theshoe, as common heretofore in some machines ofthe 'illustratedjtype. ,Theunperefastening devicesateach side of theiast-includetwo plates 44 and 46 ,eachlofmhich serves as agllide forone-f the tack drivers 24 andas a supportfor the corresponding pair .oftack fingers 32 :the iconstruction .hereinshown the;n1ates 44, which.are included in the rearmost upp -fastening devices (i. e., the deviceslocated iarthestiromthe endof the toe), are faston .the613111520,whilelthe plates 46 included in the upper- Iastening devicesthat are nearer the end of the toe are pivoted at 48 on,the armsg forswinging movements Widthwise of the shoe and are urgedinwardlybyspringsfim Each of the plates 44 and 46'carriesat its lowerend a stop 52 arranged to engage -a shoulder on the previously mentionedside clamp block 42,. It will thus be seen'thatthe stops :52 carried bythe plates 44 that are fast onthe sidearms 20 limit the inward swinging.

. movements of these arms and determine thepositions laterally of theshoe of the rearmost upperfastening devices. The stops 52 on theplates46, on the other hand, by their engagement with the blocks 42, determinethe positions of the foremost side upper-fastening devices,permittingthese devices to adjust themselves relatively to the shoe inaccordance with the positions of the swiveled blocks -42 determined bythe contour of the shoe. In the construction shown the clamp members 40are made of metal for positive engagement with the shoe, so as to affordbetter insurance of accuracy in the positioning of the upper-fasteningdevices relatively to the shoe. Each stop-52 is threaded in theplate 44or 46 which supports it to permitits adjustment laterally of the shoe bymeans of a screw driver and is clamped in adjusted position by aclamping screw 54 engaging two parts of a split bearing in which thethreaded portion of the stop is mounted.

, To assist in holding the upper until the tacks are driven, each of'the'side upper-fastening devicesin the construction herein showncarriesa clamp member 56 which clamps the marginal portion of the upperagainst the last above the clamp member 40 at the junction of the bottomface and the upper-shaping surface of the last and acts to some extentas a wiper upon the upper as it is movedinwardly; By reference to Fig.4, which shows the two members 56 thatare carried by-the foremost sideupper-fastening devices, .it will be noted thateach member 56 issupported on the plate 46below the tack fingers 32. Each member 56 isprovided with two arms 58 that extend along oppositesides of the plate.46, aportionvof one of the arms of the left-hand member being brokenaway in Fig. 4. The two arms 58 carry a pin 60-011 which there ismounted a roll 62 located in a slot 64 in the plate 46.- The member 56has an upwardlycurved end portion for engaging the upper and has in thisportion a slot through which the tack is driven, as shown in Fig. 6. Aspring 66 connected to the plate 46 and to .a ,pin 68 that xtendsbetween the two arms 58 urges the member 56 inwardly and posi-, tionsitnormally with the rol1'62 at the inner end of the ,slot .64. Anotherspring'lO connected .to the plate 46 and the pin 68 :tends to swing themember 56 about the axis of thepin 60 in the/direction todepress theupper-engaging end portion of. the member. .such swinging .rnovementofthe v member 56 is limited by engagement of portions of thearms 58 withthe plate 46 :in slots 72 in the sides of the plate. It will thus beseen that when the plate 46 is carried inwardly toward the shoe by theswinging of the arm 20 the inner end of the member :56 engages theupper'held in tensionedcondition by the gripper before the arm 20completes its inward swinging movement and that as the arm continues itsmovement the springs 66. and yield and thereafter by theirtensionserveto urge the upper-engaging portion parted by thecorresponding updraw lever 14 to close the jaws 74 on the upper and thento impart to them their upper-pulling movement. Similarly the toegripper comprises jaws 78 which are closed. and operated bye. gripperbar 80 connected to the corresponding ,updraw lever. Located between theside gripper bars 76 and at the rear of the toe gripper bar ,80 isgripperspreading mechanism of substantially the same character asdisclosed in the previously mentioned Letters Patent No. 1,029,387,whereby the side grippers are positioned initially at the properdistance apart to receive the margin of the upper at the sides of thelast and the toe gripper also is presented in the proper initialposition length wise of the last to receive the upper. This mechanismisnot herein shown in detail, but includes members 82 which engage theinner faces of the side gripper bars 76 and a roll 84, which engages therear or inner face of the toegripper bar 80, Associated with each of theside grippers are two overdraw, springs 86, only one of: which is shownin the drawings, these springs bearing against a plate 88 engaging thegripper on its outer side and thus tending to swing the grippergrippersto be swung inwardly by'the overdraw I springs to make way forthe upper-fastening devices. V For the accomplishment of one of theobjects of the present invention the construction herein shown is suchas to cause the grippers to be swung somewhat inwardly by the overdrawsprings in the course of the upper-pulling movements of'the' grippersheightwise of the last, prior 'tothe in-'" ward movements of theupper-fastening devices, Tothis end, each of theside gripperbars 76 hasat its inner side a face 92 in engagement with the member82 andarrangedin such inclined relation to the direction of the upper-pullingmove merit oflthe gripper heightwise of the last asto permit an -.inwardswinging movement of the l gripper by the springs 86 proportional to theextent of the upper-pulling movement as the latter movement takes place.A similarly inclined face 94 on the toe gripper bar engages the roll 84and performs the same function with respect tothe toe gripper. Byreference to Fig. 4 it will be seen that by the cooperative action ofthe inclined faces 92 and the members 82 the side gripper jaws arepositioned initially at such a distance apart that the jaws are locatedopposite the side faces of the last when in upper-receiving positions.As the upper-pulling movement of the grippers is effected they are swunginwardly by the overdraw springs as soon as the jaws rise above theplane of the bottom face of-the last, so that they draw the marginalportion of the upper inwardly over the edge of the last bottom beforethe upper-pulling operation is completed, as illustrated in Fig. 5. Asimilar action occurs at the toe end of the last. The portions of theupper that are to be engaged by the clamping members 56 are accordinglydrawn inward over that portion of the surface of the last against whichthey are tobe clamped by these members before the latter receive theiroperative movements. The inward swinging movements of the grippers alsocarry the gripper-releasing members 18 farther from the upper-fasteningdevices. Better insurance than heretofore is thereby afforded that themarginal portion of the upper will be clamped and held in properrelation to the last before the members 18 are operated by the incomingupper-fastening devices to release the grippers from the upper, so as toavoid any loss of tension in the upper before the fastenings are driven.It will be understood that after such inward movements of the grippersas occur during the upper-pulling operation by reason of the inclinedfaces 92 and 94 on the gripper bars, still further inward movementsthereof result from the retraction of the gripper-spreading mechanism toposition them well out of the way of the upperfastening devices afterthey are released from the upper, as illustrated in Fig. 1.

It will be evident that the driving of the tacks precisely in thedesired locations at the junction of the bottom face and theupper-shaping surface of the last requires that the last be accuratelypositioned heightwise relatively to the upperfastening devices; For thispurpose the machine is provided with a work rest comprising a member 96arranged to engage the bottom face of the last near the end of the toeand members 98 arranged to engage the bottom face of the last fartherrearwardly at the sides of the forepart. The end member 96, as in priormachines of the illustrated type, is mounted on a bar 100 which isadjustable lengthwise of the last in a holder 102, the bar as hereinshown being held in adjusted position by a screw 104 threaded in a plate106 on the holder 102 and having a pointed end 108 cooperating with rackteeth 110 on the bar. The member 96, is pivoted at 112 on thebar 100 forswinging movements heightwise of the last. A spring 114 tends to swingthe member in one direction, and a screw 116 carried by the member andbearing on the bar 100 cooperates with the spring to determineadjustably the position of the member. The side members 98, in theconstruction herein shown, are adjustable relatively to the end member96 in directions heightwise of the last, and for this purpose they aremounted on a support 118 which is itself mounted on screws 120 on thesides of the holder 102 for swinging movement about an axis extendingwidthwise of thelast." A spring 122 tends to swing the support 118'v inone direction, 7 and cooperating with the spring to determine adjustablythe position of the support there is a stop screw 124 which is threadedin the support and abuts against the bar 100.

By means of the screw 124 the last-engaging portions of the members 98may accordingly be adjusted heightwise of the last.

In view of the fact that the bottoms of lasts at the forepart arefrequently curved more or less laterally as well as lengthwise, theconstruction herein shown is further such that the members 98 engage thebottom face of the last in locations as close as is practicable to theside edges of thelast bottom, as herein illustrated at less distancesfrom the edge of the last bottom than the width of the marginal portionof the upper that extends beyond said edge. As illustrated, moreover,these members engage the last in locations opposite the points where therearmost side tacks are driven, i. e., in locations directly inward overthe last bottom from these points, so as to provide for particularaccuracy in the driving of the rearmost tacks which in practice aresometimes permitted to remain in the shoe and last until a later stagein the manufacturing operations than the foremost side tacks and the endtack. In order that the members 98 may be accurately positioned inoperating on lasts of different sizes, the construction shown is suchthat they are pivoted on screws 126 on the support 118 for swingingmovements widthwise of the last. A spring 128 located between themembers 98 forwardly of the points where they are pivoted tends to swingtheir last-engaging ends apart. To cooperate with the spring 128 inadjusting the members 98 widthwise of the last there is provided a screw130 which is threaded inthe support 118 rearwardly of the pivot pointsof the members and has a conical end portion that engages inclined faceson the members, the screw thus acting as a wedge member in opposition tothe spring 128. By adjustment of the screw 130 the last-engaging ends ofthe members 98 may accordingly be positioned at the desired distancesapart for operating on lasts of different sizes. It will be understoodthat the member 96 is also adjusted, to engage the last as near as ispracticable to the point where the end tack is driven, and that byadjustment of this member heightwise of the last as hereinbeforedescribed the desired accuracy with respect to the location of the endtack is obtained. It will be evident that when the members 96 and 98 areadjusted to determine accurately the position of the last relatively tothe devices that drive the end tack and the rearmost side tacks, thelast is positioned also with sufficient accuracy relatively to thedevices that drive the foremost side tacks.

Having described the invention, what I claim as new and desire to secureby Letters Patent of the United States is:
